guys please help me with this numerical.... i have confusion
1.An a/c obtains a relative bearing of 315deg. from an NDB at 0830. At 0840 the relative bearing from the same position is 270deg. Assuming no drift and GS of 240kt, what is the approx. range from the NDB at 0840?
a. 60nm
b. 30nm
c. 40nm
d. 50nm
the way i solved is :
time the a/c is away from station = time in sec / brg change
=> (10 x 60)/ 45
13.3min
and then dist from grnd station = GS per min. x (13.3)
is this correct way to solve...!!
please help
